In continuing to recognise Hipparchus and Minos as Platonic works, contrary to the opinion of many modern critics, I have to remind the reader, not only that both are included in the Canon of Thrasyllus, but that the Minos was expressly acknowledged by Aristophanes of Byzantium, and included by him among the Trilogies: showing that it existed then (220 B.C.) in the Alexandrine Museum as a Platonic work. The similarity between the Hipparchus and Minos is recognised by all the Platonic critics, most of whom declare that both of them are spurious. Schleiermacher affirms and vindicates this opinion in his Einleitung and notes: but it will be convenient to take the arguments advanced to prove the spuriousness, as they are set forth by M. Boeckh, in his "Comment. in Platonis qui vulgo fertur Minoem": in which treatise, though among his early works, the case is argued with all that copious learning and critical ability, which usually adorn his many admirable contributions to the improvement of philology. M. Boeckh not only rejects the pretensions of Hipparchus and Minos to be considered as works of Plato, but advances an affirmative hypothesis to show what they are. He considers these two dialogues, together with those De Justo, and De Virtute (two short dialogues in the pseudo-Platonic list, not recognised by Thrasyllus) as among the dialogues published by Simon; an Athenian citizen and a shoemaker by trade, in whose shop Sokrates is said to have held many of his conversations. Simon is reported to have made many notes of these conversations, and to have composed and published, from them, a volume of thirty-three dialogues (Diog. L. ii. 122), among the titles of which there are two--[Greek: Peri\ Philkerdou=s] and [Greek: Peri\ No/mou]. Simon was, of course, contemporary with Plato; but somewhat older in years. With this part of M. Boeckh's treatise, respecting the supposed authorship of Simon, I have nothing to do. I only notice the arguments by which he proposes to show that Hipparchus and Minos are not works of Plato. In the first place, I notice that M. Boeckh explicitly recognises them as works of an author contemporary with Plato, not later than 380 B.C. (p. 46). Hereby many of the tests, whereby we usually detect spurious works, become inapplicable. In the second place, he admits that the dialogues are composed in good Attic Greek, suitable to the Platonic age both in character and manners--"At veteris esse et Attici scriptoris, probus sermo, antiqui mores, totus denique character, spondeat," p. 32.
